To all whom it may concern:

Be it known that I, WALTER P. Lmaonnn, a citizen of the United States,residing at Pasadena in the county of Los Angeles and balifornia, haveinvented new and useful Improvements in Bumpers for Automobiles, ofwhich the followlng is a specification.

This invention relates to hinged connections between the. main bumperand its end horns, whereby the end horns may be swun relative to themain bumper to provide 0 earance space.

It is the object of this invention to pro vide a novel connectionbetween the main bum r and its end horns arranged whereby the inner endsof the end horns, when the latter are in normal position in lateralelonthe main bumper, will overlie and shut a ainst the ends of the mainbumper to provi e an exceedingly durable construction; the parts fprtermore being so arranged that the outer surfaces of the main same planeso as to present flat unbroken outer surfaces at the'connections betweenthe main bumper and its end horns, thereby providing a neat and simpleconstruction. invention will be readily understood from the fdllowing'descriptron of, the accompanying drawings 1n which:

ranged to be received within the channel of the main blumper 12.

The end horns of the bumper are hinged to the main bumper 12 so thattheymay be swun from their normal position as shown in fu lines in Fi 1 tothe osition shown in dotted lines in ig. 1. Tliese end horns are shownat 15 as formed of channel iron and are preferably suitably curved attheir outer ends so as to terminate at points slightly in front of andat the outer sides of the wheels of the automobile. The inner ends ofthe end horns of the bumper are preferably received over the ends of themain bumper 12, and the inner ends of the end horns terminate in lips 16at the upper and lower surfaces of the channel'iron comprising the endhorns. The hinged connec- 15 is provided by a bolt 17 e'xtendin throughthe lips 16 of the end horn an through the upper and lower surfaces ofthe channel iron of the main bum er, this bolt being provided with aparts in assembled relation. The pieces of channel iron 14 to which thebolts 13 for securing the bumper to the bumper sup rts are attached, arereferably retaine within the channel of t e main bumper by extending thebolts 17 through said pleces of channel iron, the latter for thispurpose referably being-provided with elongated s ots 19 so that thedistance between the bolts 13 may be adjusted to the required width.

When the end horns of the bumper are in normal position in-lateralelongation of the main bumper the inner ends of the horns abut againstthe outer ends of the main bumper thereby forming a bumper which willoffer rigid resistance throughout its length toa force exerted againstthe bumper from the front. It may be found desirable however, to employbolts 17 at the hinged connection twee: the main bumper and the endhorns which will shear at a predetermined strength, thus separating theend horns from the main bumper and prevent- .ing bending or distortionof the end horns passed on the road by another machine there is aliability of the end horns of the bumper encountering some portion ofthe other machine, but since a hinged connec tion is provided betweenthe main bumper 'and the end horns the latter will under theseconditions swing forward to the position shown in dotted lines in Fig.1, thereby avoiding injury to thebumper It is essential to thepronsmnofa-nent; bumperconstruction that the outer face of thesnme'shall' pres'ent flat unbroken sur" faces at the hinged connectionsbetween the In order 1 tone-comp ish this result the portions of themain bum or und the end horns.
